OIL BURNER I Application filed February 16, 1927. Serial No. 168,498.

Our invention relates to vaporizing oil burners, such as are used for burning liquid hydro-carbons. These burners consist of a vaporizing coil connected to an oil supply,

the vapor generated in the coil being de-' livered through a vapor-discharge or burner nozzle, producing a flame from the heat of: which the vaporizing coil becomes sufficiently heated to convert its contents into an unstable gas or vapor. casing is provided over the vaporizing coilto prevent its be;

coming too cold. Such casings as heretofore constructed were welded to the vaporizing coil. The vaporizing coils of such burners frequently burn out and must be replaced, and with such previous constructions it was necessary to replace the casing also.

In accordance with our invention, we pro-, vide a casing which is readily removable and in case the vaporizing coil is destroyed,

it is only necessary to replace such coil and no other part of the burner.

The various features of novelty which characterize our invention are pointed out with particularity in the claims annexed to f and forming a part of this specification.

For a better understanding of our invention, reference may be had to the following nozzle, and Fig. 4 is a sectional view of the burner nozzle of Fig. 3.

Referring to the drawing, a source of oil (not shown) is connected to a valve 2, to which the pipe 3 is also connected. This pipe after running the full length of the burner is bent in a coil 4 back toward the left with a spring effect between the por-' tions of the pipe extending in opposite directions. The pipe then extends back to the v left parallel to the pipe 3 and has connected around the pipe 3.

to the'end thereof an elbow 5 into which is screwed a burner nozzle 6, which is directed towardthe vaporizing coil 4:. The vaporizmg coil is removably supported on a base member 7. A. ca'sing8 having end walls 9 detachably supported on the base member and surrounds the vaporizing coil. The base member at the" rear is provided with lugs 10, overwhi ch the notches 11 in the casing fit.

The casing is provided with a saddle 20 which fits over the pipe for holding the pipe I in place. The springefi'ect of the pipe where it bends back on itself takes'care of the difference in expansion and contraction between the casim and the pipe, as the burner heats whenhghted and subsequently cools when ex-. tinguished. The casing is prevented from moving with respect to the base member by means of bolts going through holes 12 in the saddle and corresponding holes 12' in the base member. The end walls 9 of the casing are welded to the main portion of the casing. 'The' casing is provided with openings 13 to admit air tothe interior of "the casing so that complete combustion will take place. A hood 14 is pivotally mounted on the base member by means of bolts at "the end ofthe casing adjacent the nozzle 6.

This hood permits easy access to the burner nozzle 6, sothat the same may be lighted. A hollow stiffening member 15 is placed The burner nozzle 6 has an enlarged cylindrical' portion 16 which is screw-threaded into the elbow 5, and a cylindrical portion '17 of'smaller diameter extending into the elbow, A hole18 of substantially, uniform diameter extends longitudinally of the noz- The portion 17 of smaller diameter has a pluralityQof holes 19 extending there through and communicating with the hole 18. The holes 19are at right angles to the hole 18 and' are preferably of substantially the same. diameter as the hole 18. ltwill be readily seen that with this construction, 'a

flake of carbon entering any of the holes 18 or 19 will be blown through the nozzle, as all of these holes are of the same size. In order that our nozzle be entirely stopped up, there must be an accumulation of carbon flakes filling up the elbow 5 and covering all the holes 18 and 19 in the burner nozzle. The nozzle is shown as made of a single piece of metal. The construction of the nozzle forms the subject: niat ien of a divisional application, Serial No. 326,178, filed December '15, 1928.

Ne desire it to be understood that our-invention isnot limited to the particular arrangement shown anddescribed and we aim in the appended claims to cover all modifications which do not depart from thespirit and scope of our invention.

What we claim as new and desire to secure by Letters Patent of the United States is:

lQAn oil burner comprising a vaporizing c'oilhaving a burner nozzle, a base member on whichssaid vaporizing coil is removably supported acasing surrounding said coil having .endw alls, said casing being detach- 'ablyLf-astened to :saidbase member, and a hood pivotallymounted on said base at said end ofsaidcasing adjacent said nozzle.
